Heres what I need to know. Can I trim out the lug holes in a set of weld rims? They have the moving center in this set. I guess I measured wrong when I got them. The guy I bought the rear end from said it was a four and a half big five, but its 4.50 / 4.75. They almost fit in to the holes, and I know I would have to trim on the inside of the rims to make the nuts fit, but is it safe? Thanks.
